Patented Mar. 4, 1930 j UNITED STATES PATENT oFElcE ALOIS J. ZWIERZINA, OF DETROIT, MICI-IIGrN,v ASSIGNOR TO ACKERMAN, BLAESSER, FEZZY, INC., OF DETROIT, MICHIGAN, CORPORATION OF MICHIGAN SASH-OIERATING MEGHANISM Application led August 4,1926. Serial No. 126,988.

This invention relates to roller supports for automobile windows, and the object of the invention is to provide a support for the window whereby the window is yieldably held in position so it will not readily crack or break during travel over rough roads.

Another object of the invention is to provide a roller composed of two halves normally held together by a spring, the two l halves being separable against the tension of the spring to allow yieldable movement of f the window in relation thereto.

A further object ofthe invention is to provide a roller of the character described in which the two halves will readily spread apart during raising of the window thus allowing a slight flexible movement of the window in relation to the crank by which the window is raised.

These objects and the several novel features of the invention are hereinafter more fully described and claimed and the preferred form of construction by which these objects are attained is shown in the accompanying drawings in which- Fig. 1 is a view of the interior of a closed automobile body showing the window regulating mechanism in relation thereto.

Fig. 2 is an enlarged section taken on line 2-2 of Fig. 1.

Fig. 3 is a similar section showing the two halves of the roller moved apart.

Fig. 4 is a view of the spring washer.

The window comprises a glass 1 which is mounted in a metal channel 2. This metal channel 2 is provided with a half round lower edge 3 and secured to the channel 2 at one side is a guide member 4 having a iange 5 extending beneath the channel 2 and in spaced 0 relation therewith. The roller is formed in two halves 6 and 7 which, when positioned together, provide an annular half round channel 8. These two roller halves are rotatably mounted on a round pin 9 having an enlarged end 10 to prevent the roller from coming off from the pin and the pin is provided with a shoulder from which the stud 11 extends through the arm 12 and the end of the stud 11 is riveted over as shown ink Figs. 2 and 3, to

secure the pin in the arm 12. This arm 12 is connected with a window regulating mechanism which is operated by the crank 13 shown in Fig. 1; andmay be lof any approved type, the arrangement being such that rotation of the crank 13 turns the arm 12 up or down to raise or lower the window. A spring washer 14 is positioned on theV pin 9 between the roller half-7 and the arm 12 and tends yto hold the two halves of the roller together as shown in Fig.` 2. This spring washer, as shown in Fig.

4, is provided with three undulations or raised portions l5 which produce the spring action in the washer. When the twohalves of the roller are together, as shown in Fig. 2, the

channel 13 does not rest in the bottom ofthe ring down between'the roller halves tends to absorb considerable of the jar. The flange 5 f on the guide member 4 provides a rest for the roller halves in moving the sash and window downwardly and the roller is held in position at all times by the channel 3 partially en- 'gaging in the annular channel 8. When the kwindow is raised the upward movement of the arm 12 causes the halves of the roller to separate as shown in Fig. 3 thus giving a yieldable effect between the crank 13 and the window. f f j It will be understood from the foregoing that an additional object of this invention is to secure a sash operator in which the roller fills the space between the sash and the bottom of the runway in such manner that rattle or noise is eliminated at the point of connec-` tion of the roller and sash which heretofore has proven unsatisfactory. With my roller arrangement in which the roller is formed of similar halves and a spring resisting sep-v aration ofthe halves, the roller is always held in tight engagement with the edge of the sash and further is caused to engage the opposite side of the way when no strain is applied to the operating arm and it is further to be observed that, while I have described a particular type of spring for holding the roller halves under a tension, any type of spring adapted for the purpose may be Autilized without departing from the spirit' of this in- Ventioh; y u A v From the foregoing description ity becomes evident that the device is very simple and efficient in operation, will noteasily get out of order, is composed of few parts,l and Ais of consequent low manufacturing cost and provides a device which accomplishes the 'olbjects described. y i

Having thus fully described my invention,

its utility and mode' of operation, what I claim and desire to secure by Letters Patent of the United States isl. In sash operating mechanism, the com- Y v bination with a sash havinga way at its lower edge, of a rollerriding in the said way, a

shaft for the roller,' an operating arm for raising andlowering the sash fto which the shaft is fixed, the roller being formed of two half parts each independently rotatable upon the shaft, a spring tending to force the two half parts together, the two half parts being shaped to `providea peripheral groove 1n Y which the edge "of the sash liesv and the said spring -tending to force the halves toV engagement with the sash on the one side and the bottom of the way on the other whereby the said roller is held under tension in the way.

2. AIn sashV operating mechanism, the combination with a' sash havingV a way at its lower edge, of a roller riding in the said way, a shaft for the roller, an' operating arm for raising andvlowering` the sash to which the shaftjis fixed, the roller being formed of two f parts eachv independently rotatable upon the shaft,va spring tending tofforcev the two parts together, the two parts bei-ng shaped to providea peripheral grooverin which the 'edge ofthe sash is supported and the said spring tending vto force the rollerparts to engagement with the sash onthe one side and the bottom of the way on the other whereby the said roller is held under tension in the wa lIn testimony whereof I sign this specification.
